  • Publication number: 20170086111
    Abstract: Aspects of the disclosure provide systems and methods for establishing one or more Distributed Gateways located close to a location of a UE to facilitate faster packet delivery to said UE during transitions. Such transitions can include the UE transitioning its state, for example from being idle to connected to the network, but also includes operations in which the serving AP(s) for the UE changes. The method includes establishing at least two virtual network function (VNF) components (VFNCs) of a distributed gateway (D-GW), each VNFC associated with an access point (AP). Each VNFC buffers packets directed to the wireless device. The method further includes selecting at least one AP for serving the wireless device, and forwarding the buffered packets from the VNFC associated with the selected APs to the selected APs for forwarding to the wireless device. Packets buffered at the VNFCs of non-selected APs are discarded.

  • Publication number: 20170086049
    Abstract: Embodiments provide high reliability and responsiveness by dedicating resources both at the RAN and the core to provide high throughput, low latency communication for a critical communication service. Radio resources can be allocated to the machines in the ambulance as and where needed to guarantee the required QoS. Further, as the route an ambulance will follow to the hospital is known or can be predicted, this information is exploited by embodiments to further reduce communication delay by instantiating VNFs closer to the edge where and when they are needed. Further, end-to-end paths can be configured in advance between each access point and a hospital. In some embodiments, core network functions can be isolated from other traffic in the network so that the performance of the critical communication service is not impacted by other services. Low latency can be further enhanced by customized processing of the traffic.

  • Publication number: 20170055276
    Abstract: A hierarchical link scheduling system and method is provided. A central controller gathers network information, including global parameters and long term demands, and determines an initial schedule for link activation based on these variables. A scheduler receives the initial schedule and modifies the initial schedule based on local parameters, inter-schedule negotiation, or other short term or localized requests. The scheduler activates the links according to the modified schedule. Accordingly, the scheduler can be responsible for modifying the initial schedule provided by central controller with localized or short term requests or demands, and providing the necessary parameters to enable link activation between nodes according to the modified schedule.

  • Patent number: 9572042
    Abstract: A spectrum channel sharing system may coordinate a shared usage of one or more spectrum channels between a first communication system and a second communication system. The first communication system may transmit a request to the second communication system to clear communication traffic associated with the second communication system from a spectrum channel. The first communication system may then initiate a communication session on the spectrum channel after the communication traffic associated with the second communication system has been at least partially cleared from the spectrum channel.

A TCSP control element sends to a downstream control element, a request for a portion of the infrastructure to be allocated to the TCSP by an infrastructure provider (InP) and receives a response from the downstream control element providing access to and control of the allocated infrastructure. The TCSP control element can pool the allocated infrastructure with other resources allocated to the TCSP and/or communicate with an upstream control element for providing access to and control of the allocated infrastructure to the VNO. The downstream control element is a local InP control element or a downstream TCSP control element. The upstream control element is a VNO control element or an upstream TCSP control element.

  • Publication number: 20160353281
    Abstract: An aspect of the disclosure provides a method of admitting a session from a user device subscribed to a service with a virtual network operator. The method includes receiving a service request from said user device at an Access Point and selecting a network function Authentication and Authorization (AA) function (AAF) to confirm the user device is authorized for the requested service, and transmitting the request to the selected network function AAA function. The AAAF which processes the request may reside with the virtual network operator (VNO). However, the VNO may share its AAA database with other network entities (for example, Telecom Connectivity Service Providers (TCSPs) or InPs), and allow those entities to perform the AAA functions.

  • Publication number: 20160353226
    Abstract: There is provided a method and system for management of Machine Type Communication (MTC) events. The system and method enables the detection of a state of the MTC event, correlating the state of MTC event with a Virtual Network Function (VNF) state of a VNF configured to mitigate the MTC event and transitioning the VNF to the VNF state which correlates with the MTC state. In this manner, the VNF can be in a configured and active state in advance of the MTC event reaching a critical state, thereby enabling mitigation of the MTC event prior to reaching the critical state.
